The Theoretical Calculation and Experimental Study Of Grooved Waveguide Ferrite Phase Shifter

利用铁氧体矩形波导中的场方程 ,导出了铁氧体传输段的输入阻抗表达式 ,结合横向谐振技术和等效导纳概念 ,导出了铁氧体槽波导移相器计算模型的特征方程。在对计算模型进行了新的修正后 ,我们编程进行了计算 ,修正后的计算值与实验结果较吻合。

This article, with the appling of equation in the waveguide filled with ferrite, derived the expression of input impedance of the ferrite transmission line, then, joined with the translate resonance technique, obtained the characteristic equation of the model of the grooved waveguide phase shifter. We carried out calculation and made a new effective correction. Corrected calculation data conformed to the experimental date well.
